Docker CentOS image does not auto start httpd

You need to run apache (httpd) directly - you should not use init.d script.

Two options:

you have to run apache in foreground: /usr/sbin/apache2 -DFOREGROUND ... (or /usr/sbin/httpd in CentOS)
you have to start all services (including apache configured as auto-run) by executing /sbin/init as entrypoint.

Add this line in the bottom of your Dockerfile to run Apache in the foreground on CentOS

ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]

apache docker centos dockerfile

Simple Dockerfile to run httpd on centOS
